I've narrowed it down to some interaction between Terminal and Emacs 24. You can discount Claws and Gnome Do.
I can reproduce this every time with this recipe: * reboot * login * hit Alt to bring up the launcher * start up a Terminal * In the Terminal, enter "emacs -q" to bring up a vanilla Emacs 24 * Go back to the Terminal and maximize it (i.e. hit the third button from the left in the menu bar, the square) * Go to the global menu bar and double click as if de-maximizing the Terminal * X crashes -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1284134 Title: Xorg crash Status in “xorg” package in Ubuntu: New Status in “xorg-server” package in Ubuntu: New Status in “xserver-xorg-video-vmware” package in Ubuntu: New Bug description: I use the Nouveau theme of Gnome-Do, and I bind its invocation to Alt- Ctrl-Space.
